In Portland, the market for nitro is going nuts, thanks largely to White Cap and Nobl Coffee, a wholesaler based in Exeter, New Hampshire. The two brewers are selling their nitro to local businesses as varied as Bayside Bowl, the Portland Food Co-op, Otherside Delicatessen, Ri Ra and, of course, coffee shops such as Arabica and Coffee By Design. Many of these spots are selling growlers of nitro as well.
